Engineering firms Thornton Tomasetti, Inc. and Weidlinger Associates, Inc., have merged. The combined firm will have 1,200 employees operating in 34 cities internationally and will remain headquartered in New York City. Terms of the deal were not disclosed.

“Combining our firms brings together two highly respected and recognized talent pools, creating significantly greater potential for growth and innovation than either firm could achieve alone,” said Thomas Z. Scarangello, chairman and CEO of Thornton Tomasetti. “Both our cultures have a ‘one firm’ approach, bringing the best qualified team to bear on any challenge presented by any client. Our more diverse merged expertise allows us to address a wider range of client needs, while offering enhanced breadth and depth of services and extended geographic reach.”

The new firm will operate under the Thornton Tomasetti name; three practices continue to be marketed with the Weidlinger brand where it carries strong industry recognition: Weidlinger Applied Science, Weidlinger Protective Design and Weidlinger Transportation.

“Just as important as our complementary suite of services and geographic footprints is our compatible cultures,” said Raymond P. Daddazio, president and CEO of Weidlinger Associates. “While no two firms are exactly alike, ours bear many similarities – including the drive for innovation, long-standing entrepreneurial spirits, and shared values in philanthropy, employee enrichment, embracing challenges and a desire to make lasting contributions. We’re also different enough in ways that our combination will inspire us to think and work in new and exciting ways.”
